Work WorkPro PULSE DRIVE 2004 - 4‑Channel Class‑D DSP Power Amplifier (4 × 500W @4 Ohms)

The WorkPro PULSE DRIVE 2004 is a high‑power 4‑channel Class‑D amplifier with integrated DSP, engineered for professional audio installations, venues and live sound applications. Delivering 4 × 500W at 4 Ω with efficient Class‑D amplification, this compact 1U rack‑mount unit offers both performance and flexibility.

Built‑in digital signal processing enables precise tuning and optimisation of each channel, including EQ, crossover filters, delay, dynamics and noise control — eliminating the need for external processors in many applications. The intuitive DSP can be accessed via the front OLED display or remotely over Ethernet network control using PC software.

For more demanding setups, the amp supports bridge mono mode, delivering 2 × 1000 W at 8 Ω for subwoofers or higher‑power speaker zones. A comprehensive protection suite guards against thermal overload, short circuit and power‑on/off noise, ensuring reliable operation in professional environments.
